ing curlers of the type mentioned have proven
unsatisfactory because in use the roller or latch
15 mg means has a round peripheral surface which
does not grip or sufficiently engage the end of the
mandrel to prevent slippage of the roller and
clamp. These objections have been overcome and
an e?icient clamping means provided by em
ploying a roller or disk of polygonal form which
20 cooperates with the tubular. end of the mandrel.
Such a polygonal or, to be more specific, octag
onal roller readily snaps over the end of the
mandrel and seats itself in position. Such an
octagonal roller is further advantageous; since
as at l9 and 20' respectively, to facilitate the pas
sage of air through the device and hair.
In the use of my improved curler, while the
jaw’ I5 is raised, the hair is wrapped about the 15 ,
mandrel l4 suiiiclently to anchor the hair there
on, after which the jawis clamped in closed po
sition and the wrapping of. the hair continued
about the tube and jaw. when the wrapping is
completed, the ball or clamp I1 is pressed toward 20
the free end of the mandrel and the roller is
cammed over the edge of the mandrel and
slipped into the adjacent open end thereof, ef-_
,fectively clamping such bail or clamp securely
and in an accurately centered position. The 25

Referring to the drawing, the improved roll
